Three Set Points (Electro-Mechanical Relays)Option 3017-M
Three Set Points (Solid-State Relays)
Option 3017-P
This option provides three alarm set points with solid state relays. This option board slots into the upper slot of the panel meter box.
The upper terminals are clearly numbered 13-28 to differentiate them from the lower terminals. Only normally open contacts are
provided, which means that should the contacts be closed and the power fails, they will revert to a normally open condition. The
relays are rated at 400V AC /DC @ 0.5A. Visual LED alarm indication is provided on the panel meter front. For connection wiring
details, see diagram “P” on page 20. Connect wires for AL1, AL2 & AL3 only.
This option provides three alarm set points with electro-mechanical relays. This option board slots into the upper slot of the panel
meter box. The upper terminals are clearly numbered 13-28 to differentiate them from the lower terminals. Both normally open and
normally closed contacts are provides with each relay. The relays are rated at 250VAC / 30VDC @ 2A. Visual LED alarm indication is
provided on the panel meter front. For connection wiring details, see diagram “M” on page 20. Connect wires for AL1, AL2 & AL3 only.
This option allows the operator to zero the display at any time and continue the measurement from that zero point. This option is
activated "ON" or "OFF" in the "Opt” menu during programming (see page 8).
During normal operations, pressing the “star key” for 3 seconds will zero the display. The display can also be zeroed via an external
potential free contact (see page 6 for connection details). The display can be zeroed at any time over and over again. If the analog
output option is fitted, the output will follow the display. Note that this option cannot be used in conjunction with option 3012, nor will
this option be available if ‘d.tot’ or ‘p.int’ is selected in the input menu.

This option is similar to option 3017-P, but contains four relays (see option 3017-P). For connection wiring details, see diagram “P” on
page 20. Connect wires for AL1, AL2, AL3 & AL4.
Four Set Points (Solid-State Relays)Option 3018-P
This option is similar to option 3017-M, but contains four relays (see option 3017-M). For connection wiring details, see diagram “M”
on page 20. Connect wires for AL1, AL2, AL3 & AL4.
